Specification of Letters Patent.

Patented July 6, 1915.

T0 all whom it may concern: v

Be it known that we, ADOLPH BERNARDINI and Winnie L. E. Knnrrnn, citizens of the United States, residing at Hoboken, in the county of Hudson and State of New Jersey, have invented certain new and useful lmprovements in Tape-Reels, of which the fol lowing is a specification.

This invention relates to cased tape reels, and its novelty consists in the construction and adaptation of the parts, as will be more fully hereinafter pointed out.

ln the tape reels known to us, the tape is rolled upon a drum into which the crank handle is folded. ln tape reels of this class,

the crank handles are diiiicult to unfold, especially if the user happens to havestiii' ngers or is wearing gloves; or, if the handle is easily manipulated, it does not readily maintain its closed position. We have overcome these difficulties by providing means arranged outside of the drum so that the han* die is readily brought yinto an operative position, even under adverse circumstances.

Yin the drawings, Figure 1 is atop plan view' of a tape case embodying the invention. Fig. 2 is a bottom plan view thereof. Fig. 3

vis a diametric section on an enlarged scale on the plane of the line 3 3 in Fig. 1. Fig. is a detail bottom plan view of the tape drum.

1n the drawings, 1 is a substantially cylindrical case made of anysuitable material as' leather, and adaptedto contain the other parts hereinafter mentioned. An opening 2 is provided in its outer edge to allow for the unwinding of a tape 3. The side plates i and 5 of the cylindrical body of the case each have an inner central aperture, and about the peripheries of these apertures are mounted members adapted to serve in the usual manner as bearings for the rotatable parts, as hereinafter described.

The tape drum consists of an outer plate 7 and a cylindrical body 8, the tape being wound upon the latter. Upon the plate 7 is carriedva crank 9 for the` instrument and which crank is hinged upon a pintle 10 and provided with a handle ll'swiveled upon a from the plate 7 is a hollow axial sleeve 11i threaded'externally and internally.

A portion of the drum cylinder is bent inl wardly to form a leaf spring 15. A push pin having a conical termination 16 and a finger piece 17 is mounted in the plate 7. The conical termination of this pin is in which spring is also in enga-gement with the handle 11 when the latter is folded and is inside of the drum.

A leaf spring 18 secured to the lower sur, face of the plate 7 is provided with an upwardly extending flange 2O which passes through an aperture in the plate '7 to contact with the crank 9 and which spring is compressed. by such contact when the latter is brought to a position to bring the handle inside of the drum.

A. post .21 eccentrically set within the drum is provided as a means for holding the end of the tape. A screw 22 threaded to fit the internal threads of the axial post 14 is provided with a bearing surface 23, which is adapted to rotate on the bearing of the lower side of the case 5.

. constant engagement with the leaf spring 15,. I

Means are provided for determining the y the external threads of the axial post 14.

When this sleeve is placed upon such axial post and rotated to the desired position the screw 22 is moved inwardly only until it contacts with one end of the sleeve.

` ltis believed the operation of the device will be clear from the following description: When the handle crank is not in use, it is turned to the position shown in full lines in Fig. 3, in which case, the spring 15 en ages the handle 11 and holds it within the rum. lf, now the projecting end 17 of the push pin is pushed inwardly, its conical termination 16 will bear against 'the spring 15, thereby causing it to be disengaged from said handle, releasing the crank. lnasmuch as the crank 9 when in its inoperative position has forced inwardly the spring 18, this spring will react when the handle is released to throw the crank outward, as indicated in dotted lines in Fig. 3. f y
